Abstract
We have realized a 200GHz 4×4 focal plane array (FPA) by using super-regenerative receiver (SRR) pixels made of 65nm CMOS for mm-wave imaging applications. With 16 pixel elements constructed on PCB, the FPA consumes 215mA under 1V power supply. Such realization is made possible by carefully analyzing the super-regenerative interference (SRI) commonly observed in close-spaced SRRs and applying a newly developed quench synchronization scheme to suppress the undesired SRI.
